TERMINAL CLIP FOR ELECTRIC BATTERIES.

Specification of LettersPatent.

Patentci'bec. 12, 1911.

To all whom itmay concern:

Be it known that I, CHARLES E. AVERY, a citizen of the United States ofAmerica, and residing at Jersey City, in the county of Hudson and Stateof New vented acertain new and useful Improved Terminal Clip forElectric Batteries, of which the following is a specification.

My invention relates more particularly to that class of spring clamps orterminal clips which are made of spring wire bent up to the desiredshape to be secured to the electrodes of batteries, particularly drybatteries, to receive and grip the bared ends of the conductor wires,etc. An example of a wire clamp or terminal clip of this charactor isillustrated and described in the Young Patent No. 311,630, dated Feb. 3,1885.

The main object of my invention is to so construct the device that itmay be attached with strength and security to either electrode of thebattery, and used with great convenience for the connection ordisconnection of the conductors.

In the accompanying drawing, Figure 1 is a perspective view of one formof my improved terminal clip; Fig. 2 is a side View showing the mannerof securing the clip to the zinc electrode of a dry battery, which ispartially indicated in section; Fig. 3 is a perspective view of one ofmy clips shown secured to the carbon electrode of a dry battery; Fig. 4is another perspective View of the same clip, detached; Fig. 5 is anelevation of a modification.

In the particular form of clip illustrated in the drawings, the clampingportion is in essential respects, substantially the same as shown in theabove mentioned Young patent, that is to say, the wire E is firstdoubled,

and the doubled portion is then turned or bent so as to form a springhow 6, the downwardly extending portions f, f of which are separatedsufliciently to enable them to receive the portions g, 9 between them;in the portions f, f, is formed a sharp bend f and in the portions 5 gis formed a reverse bend 9 The elasticity of the spring how 6 causes theportions 7, f to tend to spring outward, but when the saidportions f, fare pressed inwardly, the bend f is'caused to pass the Jersey, have1noutside of the case,

to the zinc, I

bend g and together they form an eye .or socket for the reception of theline-wire d, which is finally clamped by the tensioning of the portionsf, f to spring outwardly. Each of the portions or legs g, g at the endof the wire is continued down to form an eye it, it, one concentricallywithin the other, thus forming a double-eye, as shown in Figs. 1, a and5. This double eye provides a strong means of attachment electrode. Inthe ease of the Zinc, it may be riveted or soldered, while in the caseof the carbon electrode, C, Fig. 3, the double of the clip to either 7aid of the usual screw S, washer and nut. In. Fig. 2, I have indicatedthe terminal clip as soldered to the zinc case Z, and if desired thiszinc case may be suitably indented to receive the securing end of theclip on the ore. P is the usual paper inclosure. In the case of theterminal clip to be thus attached prefer to' give the looped bent freeendof the portions f, f, an upward bend P, so that it will not contactwith the top of the battery when pressed down for the insertion orremoval of the line wire.

In each terminal clip, but more particularly that intended to be secured'tothe carbon electrode, I form a backwardly projecting sharp point M,Fig. 4 on the end of the Wire forming one of the eyes or on each wireend, to be embedded into the carbon and pre- Vent the clip from swingingaround on the securing screw S. If desired, a strengthening band m maybe secured around the bends forming the loop e, as shown in Fig. 5.

I claim as my invention 1. A battery clip formed of bent spring wire andhaving at its securing end concentric rings forming an eye.

2. A battery terminal clip formed of bent spring wire, the ends of thewire being coiled into concentric rings to form a securing eye.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses.
